Duolok

The Duolok® range of stainless steel tube fittings are two-ferrule design delivering leak-tight tube fitting performance that can have a significant impact on quality, productivity and cost. These high performance tube fittings have been designed to intermix and interchange with Swagelok® fittings component-by-component.

The Duolok® tube fitting design from First Hose comprises four precision-machined components: body, front ferrule, back ferrule and nut. When assembled, the double ferrule design has a staged, sequential swaging action, which compensates for the variation in tubing materials, including the hardness and thickness of the tube wall to provide leak-tight connections.
